Senior BJP leaders today jumped to beleaguered Rajasthan Chief Minister Vasundhara Raje's defence with Finance Minister Arun Jaitley saying nobody is "tainted" and the party questioning authenticity of documents, showing her to have backed Lalit Modi's application for immigration to the UK.

"There is nobody who is tainted please," Jaitley told reporters at the Delhi airport after his return from the US.

Another senior minister, M Venkaiah Naidu, said the Narendra Modi government was working in the "most honest and transparent" manner blamed some "unhappy people" for the outcry over Raje's help to the former IPL boss.

"As far as party is concerned everything is happening positively," he said as reporters sought to know BJP leadership's stand on the raging row. Their defence of the formidable Rajasthan leader, who has led party to its biggest Assembly as well Lok Sabha win, came after she dismissed media reports against her as "untrue" and aimed at "harming her politically"
